What is ProtoNote?
ProtoNote is a feedback platform built for people who create with AI. Instead of sending screenshots or attachments around, you upload what you just built — an HTML file, a Markdown document, an image, or a PDF — and share a single link. Your work is hosted for you and presented like a real product, opening on any device with a proper preview in Slack.
How it works
- Upload — Drag and drop your files, or tell Claude "make this a ProtoNote" and get the share link back in chat. Multiple files become pages of one project, each with its own notes. Folders keep your prototypes organized instead of lost in chats.
- Share — Send one link. Reviewers need no account; they type their name and start. You'll see who viewed and when, right on your dashboard.
- Get notes — Notes pin to the exact spot on the exact version, appearing live as your team reviews. Ship v2 and old notes stay where they belong. Notifications arrive as notes and replies come in.
The feedback loop
Feedback goes back to work. Pull your open ProtoNotes into Claude through the MCP connector and apply the changes — reviewers stay in their browser, you stay in your chat.
